If you want to combat LotR, don't reply to his posts

Simply put, if he really does bother you, just ignore him. I grew up with 2 siblings and my parents were very wise to point out occasions where someone was bothering someone else and getting a kick out of it. This is definitely what LotR is doing, having seen (and, I'll admit, done) it all the time as a kid.

His only enjoyment comes from making ridiculous statements and having people respond, outraged to them. If you don't let him make you angry, he will stop enjoying posting and leave.

In the words of my dad, "It takes two people to make you angry - you have to agree that they are making you angry." The only fun he derives is that which he gets from making us angry at him and starting fights.

Of course he does have some value as comic relief as has been mentioned before.
